Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

Advanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

AKT1 Phosphorylates FDX1 to Promote Cuproptosis Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study demonstrates that copper activates the AKT signaling pathway, which inhibits ferredoxin‐1 (FDX1), a key regulator of cuproptosis. AKT1‐mediated FDX1 phosphorylation not only abrogates FDX1‐induced cuproptosis and aerobic respiration but also promotes glycolysis.

RNF112 Facilitates Ubiquitin‐Mediated Degradation of c‐Myc, Suppressing Proliferation, Migration and Lipid Synthesis in Bladder Cancer

Advanced Science, EarlyView.
RNF112, an E3 ubiquitin ligase, is markedly reduced in bladder cancer (BLCA). It curbs BLCA cell proliferation, migration, and lipid production primarily by enhancing ubiquitin‐dependent degradation of c‐Myc. This degradation inhibits c‐Myc's role in upregulating ACLY, a crucial enzyme for lipid synthesis, highlighting RNF112's potential as a ...
